While it's obvious that the entire spectrum of physics involved in the projectile to
target interactions are very complex, there are two basic assumptions that are
accepted as "culpable factors" in hollow point bullet FTO's;
One is an effect of "plugging". This is where the hollow point cavity itself becomes
filled with foreign materials, i.e. clothing, etc., thus preventing the cavity from
"filling" with intended target material (i.e. animal or human tissue(s))
The second issue, and far more viable, is that FTO's are mostly a result of the
bullet not having enough "energy" or "velocity" to facilitate the amount of internal
force needed to cause the bullet to expand as intended. In other words, by the
time the bullet enters the target, travels enough distance to fill and pressurize the
hollow point cavity; the bullet has lost the "critical mass" moment, and fails to open
altogether.
This has the potential to change every hollowpoint in the world. It corrects a serious design flaw in every hollowpoint ever designed. Impressive.
